WALTER LLOYD, OF ANTIGO, WISCONSIN.

ROAD MACHINE FOR SNOW.

Application filed September 12, 1924. Serial No. 737,512.

To all whom it may concern:

Be it known that I, WALTER LLOYD, a citizen of the United States, andresident of Antigo, in the county of Langlade and State of Wisconsin,have invented certain new and useful Improvements in Road Machines for iSnow; and I do hereby declare that the following is a full, clear, andexact description thereof.

This invention relates to road machines and is particularly directedfora machine adapted to operate upon a snow covered road. j

Objects of this invention are to provide a roadmachine for handling snowwhich will operate upon the roadway in a great variety V of ways so asto render it suitable for travel,

which is adapted to pack any light snow that may be upon the roadway orwhich will scrape the snow from the roadway,iwhich will roughen up andremove hard frozen cakes from the roadway, and which is easily operated,and may be drawn over the roadway at a relativelyhigh rate of speed.

An embodiment of the invention is shown in the accompanying drawings, inwhich Figure 1 is a side elevation of the device. Figure 2.is a planview thereof.

Figure 3 is a sectional view on theline 33 of Figure 2.

' Figure 4 is a sectional View on the line 4-4 of Figure 3. p v Figure 5is a detail of the adjustlng means and support for the rear scraper.

The machine comprlses two s de frame members 1 and 2,-.the right handside frame member 2-being materially longer than the left frame member 1These side frame members are provided with runners 3 (see Figure 4)which, if desired, maybe provided with downwardly extending ribs 4 toaidin preventing slipping of the machine while in no way interferingwith the free sliding motion thereof. These side frames are joined by aseries of bracing members 5, 6,

and 7 as may be seen from Figure 2 to se- ,cure the desired rigidity,such bracing members being provided with suitable triangular reinforcedends, as illustrated in Figure 2. A tongue 9 is secured between suitableclips and by braces to the front member 8 and, if desired, this frontmember may be pivotally, carried in .apertured lugs or bosses 10 formedin the forwardends of the members 1 and 2, as shown inFigure 1, so as to1 permi .JIOQkiQg mQQ-QQ ft c ongue 9,2 It

of horses that it is of material length, andobviously where the tongueis adapted for attachment to a tractor, it maybe materially shorter. Itis merely a means of transmitting traction effort to the machine.

The side frame members 1 and 2 are provided with spaced guides 11 and12, respectively (see Figure 1) within which crossheads 13 and 14 areadapted to travel. These crossheads are secured to a slanting knife 15which is set diagonally of the ,machine, as illustrated in Figure 2. Thecrossheads are apertured and threaded and receive the threaded adjustingrods 16 which extend vertically and are carried in suitable bearings.The upper ends of these rods are provided with bevel gears 17 which meshwith corresponding bevel gears carried by a transverse shaft 18, suchshaft being provided with a manipulating hand wheel 19 at its outer endpreferably on the right side, as shown. -By this means, therefore, theheight of the blade may be accurately an easily controlled by theoperator. The rear portion of the side frame members 1 and 2 areprovided with relatively heavy bearing portions 20 (see Figure 2')within which trunnions 21 are journaled. These trunnions are rigidlysecured to the rear scraper 22. This scraper is set diagonally, slantingtowards the right and towards the rear ;portion ofthe machine, as may beseen from Figure 2.

Further, it will. be noted from Figure 3 that the scraper isprovidedwith marginal flanges for'reinforcement and with a beveledbottom edge. The angular adjustment of the scraper is easily secured byproviding apertures through the trunnions 21 and corresponding apertures23 in the stationary hubs or bearing portions 20 (see Figure 5.) Pins 24are slipped through the appropriate apertures and thus lock the scraperbar at the desired angle.

At. a point intermediate the. front knife15 and the rear scraper 22, theside frames 1 and 2 are found provided with guides 25 within whichcrossheads 26 are slidably carried, as may be seen from Figure 4. Thesecrossheads carry the shaft of a rotary memprovided with a sprocket wheel29 which is connected by means of a chain with sprocket wheel 30 carriedby the driving shaft 31 of an engine 32 or suitable motor. If desired,an idler sprocket wheel (see Figures 1 and 2) may be provided on aspring urged rock shaft 34 to secure the requisite tension in the chaindrive irrespective of the adjustment of the crossheads 26. As will beseen from Figure 4, the crossheads receive the threaded rods 35 by whichtheir vertical height may be adjusted. The upper ends of these rods 35are provided with bevel gears 36 which mesh with corresponding bevelgears carried by a transverse adjusting shaft 37. This transverse shaft57 is provided with an adjusting hand wheel 38 by which the exact heightof the roller 27 may be most readily secured. Immediately rearwardly ofthe roller 27 a pair of vertical screws or rods 39 are positioned. Theserods, as may be seen from Figures 1 and 2, are provided with bevel gears10 at their upper ends which mesh with corresponding bevel gears carriedby a transverse adjusting shaft 41. This adjusting shaft is providedwith a hand wheel 12 by which the screws may be readily rotated. Thescrews each carry a cross head 4-3 which is connected by means of a link44 with the rear end of a curved shield plate 45. This shield plate, asmay be seen from Figure 3, extends from a point materially in advance ofthe roller 27 to a point rearwardly thereof and is downwardly curvedadjacent its rear end. It is hingedly mounted upon a transverse shaft a6adjacent its forward end and by means of the screws 39 its setting maybe easily controlled.

The operation of the apparatus is as follows :If it is desired tooperate upon hard packed glassy roadways, the mechanism is set asillustrated in Figure 3. Under these conditions, the knife 5 scrapes upthe ice and such ice flows upwardly and rearwardly over the knife. Itimmediately encounters the rapidly rotating breaker roll 27 which breaksit up into smaller particles easily disposed of. These pass below theshield plate 45 and are engaged by the rear scraper 22 and pushed fromthe roadway due to the slanting setting of such scraper bar. The factthat the ice slabs are broken into small portions by the roller insurestheir easy handling by the rear scraper bar and prevents the riding of aslab of ice over the rear scraper bar. Even if ice is left upon theroadway by the machine it nevertheless will be sufliciently roughened upand scrapped to afford a secure grip or hold for the wheels of vehicles.

Another use of this machine may be had when snow has just fallen and isrelatively light. Under these conditions, the forward knife 15 may :beelevated, and the shield plate 15 may be set either in its elevated orin its lowered position. If it is desired to pack the snow, the shieldplate is lowered and the snow is packed downwardly against theroadway,the rear scraper 22 smoothing off any uneven portions. However,if it is desired to scrape the snow from the roadway, the shield plate45 is elevated and the rear scraper engages the snow and sweeps itsidewise from the road. The machine is capable of other uses in handlingthe snow or ice on a roadway, but it is thought that the methods of useenumerated above will give a fair idea of the versatility andeffectiveness of the machine.

It will thus be seen that a machine has been provided for operating uponsnow roadways which may be easily controlled, which may be adjusted totreat or operate upon the roadway in a variety of ways, and which may berapidly drawn along the roadway and will prepare it in a manner suitablefor subsequent traffic.

Although the invention has been described in considerable detail, it isto be understood that the invention may be variously embodied and is,therefore, to be limited only as claimed. 1
